APPARATUS FOR INSTANTANEOUS STEAM-GENERATION.

SEEGIFICAIION forming part of Letters Patent No. 445,222, dated January27, 1891.

Application filed August 11, 1890. Serial No. 361,660. (No model.)Patented in Germany March l3 1890 N0. 51,952-

To all whom it may concern.-

Be it known that I, HERMANN FRIEDRICH CONSTANTIN Hess, a subject of theDuke of Anhalt, German Empire, residing at Bernburg, Duchy of Anhalt,German Empire, have invented new and useful Improvements in Apparatusfor Instantaneous Steam-Generation, (for which I have obtained LettersPatent in Germany, dated March 13, 1890, No. 51,952,) of which thefollowing is afull, clear, and exact description.

The apparatus hitherto employed for cleaning conduits for liquids, andespecially beerconduits, consists of a steam-boiler mounted on a wagon,which is driven to the locality, and is connected by means of a longrubber hose to the beer-condu1t. The steam is then generated in theusual way by heating and passes through the hose into the conduit. Thisprocess is not only tedious, but renders the proprietor of the saloondependent upon the people making this cleaning their business. Moreover,it can only be carried into practice in larger cities, as only there abusiness of this character could exist. Another important drawback isthat the steam is considerably cooled off on its way to the beerconduit,so that only after a comparatively long action of the steam is thesterilization of the conduit obtained. These disadvantages make thehitherto usual manner of cleaning the beer-conduits not only veryinconvenient and unreliable, but also highly unprofitable for thesaloon-keepers.

The object of my invention is to remedy these disadvantages by theconstruction of a steam'generator which can be used by everysaloon-keeper without a license for the use of boilers and at smallexpense for the cleaning of his beer-pipes. I have illustrated anapparatus of this nature in the annexed drawings, which form a part ofthis specification, and wherein- Figure 1 shows a side view, partly insection, of the generator. Fig. 2 shows a side View of the generator andone manner of feeding the same, and Fig. 3 shows the application of theapparatus to the cleaning of beer-pipes.

My invention comprises, primarily, an iron or copper block or bolt whichis adapted to be placed in a red-hot condition within a very strongcylinder, wherein water is fed at the top to generate steam, or at thebottom when it is desired to produce superheated steam. The cylinder A,preferably made of wrought-iron, phosphor or manganese bronze, andclosed at its lower end, is provided at its upper end with a steam-tightclosing headpiece B, carrying one or two discharge or exhaust pipes 11I). Closely to the bottom of the cylinder A is arranged a cock at, whichconnects through hose g with a pressure-pump or high-pressurewater-conduit. If two discharge-pipes b b are arranged on the headpieceB so that two conduits can be cleaned simultaneously, only one of thedischargepipes will be provided with a cock 0, thus preventing, evenwith the highest steam-pressure, an explosion of the generator. 1

If the apparatus is only intended to clean one conduit, and isconsequently provided with only one discharge-pipe, I prefer for safetyssake not to arrange a cock in this discharge-pipe.

The wrought-iron or copper block or bolt D is preferably formed with aprojection cl, in which a circular groove is provided, or a transversehole is drilled, so as to allow of its convenient insertion by means ofa hook into the cylinder when heated red-hot.

The cylinder A can be provided with feet, or preferably with a stud E,resting in abearing 0, secured to some part of the bar, Figs. 1 and 3,so as to allow of a rotary motion being imparted to said cylinder.

The operation of the apparatus is as follows: After removing thehead-piece B the block or bolt D is taken out of the cylinder A andheated in a fire. This can be conveniently done in the kitchen. fire,which will be in most cases always ready for this purpose. The red-hotblock or bolt D is then inserted into the cylinder A, and itispreferable to make its lower end rest on a stud, as shown in dotted linef, Fig. 1, so thata small space is provided for the water between thelower end of the block or bolt and the bottom of the cylinder. The blockor bolt is constructed so as to leave a small space free between itsouter surface and the inner wall of the cylinder. After screwing thehead-piece B steam-tight on the cylinder A and connecting the dischargeor exhaust pipes 12 and b by means of rubber hose (0' with themouth-pieces of the draftcocks F F, Fig 3, I admit water into thecylinder by the way of the feed-pipe g and the cock a. The red-hot blockor bolt D will at once convert the water coming in contact therewithinto steam, and as the steam will travel upward alongside the hot blockor bolt only perfectly dry superheated steam will pass into thebeer-conduit. As the steam is generated instantly upon the feeding ofthe water and the block or bolt D is heated and placed in the cylinder Abefore the rubber hose is connected to the draft-cocks, the wholecleaning process, during which no beer can be drawn, will only takeabout one minute and a half. Consequently the bar-keeper will be able toclean the beer-pipes at any time,-

even during the busiest time of the day.

In the process as just described I have taken it for granted, of course,that a highpressnre water-pipe or a pressure-pump were available toforce the water into the cylinder. It may happen, however, that thesefeatures are not available in some places. In order to render myapparatus also applicable in such places, I have devised the arrangementshown in Fig. 2. Alongside the cylinder A, I have arranged awater-receptacle G, the bottom of which connects through pipe g with thelower part of the cylinder A, while its upper end connects through pipeg with the upper end of the said cylinder. On the water-receptacle G,which is closed at both ends, I have provided a funnel H, connecting bymeans of the cook it with the receptacle. The feed-pipe g is providedwith the cook a. The receptacle G is filled with water to themouth-piece of the pipe g, the cock at being meanwhile kept closed.Subsequently the cock h is also closed. After inserting the redhot blockor bolt D in the cylinderA, closing the head-piece B, and connecting thedischarge or exhaust pipes 17 and b by means of rubber hose a to thedraft-cocks F F, the feeding-cock at is opened. The water flows from thereceptacle G under thehot bolt D, and evaporates partially by contactand partially by radiation, and the steam thus produced will then flowthrough the beer-conduits. As during this process part of the steam willalso pass through pipe g and enter into the receptacle G above thewater, the pressure at the lower end of the water column will berelieved, and the water can consequently flow into the cylinder A. Asthus constructed, the apparatus may be used by the saloon-keeper withoutthe aid of a pressure-pump or a high-pressure water-conduit. As inconsequence of the direct contact of the water with the'red-hot iron alarge quantity of oxide is formed, which will loosen itself and collecton the bottom of the cylinder A, it will be desirable to arrange thelatter so that it may rotate on the stud E. Before inserting the hotblock or bolt the cylinder is reversed, so that the oxide may beremoved. This generator can of course also be used for purposes otherthan the one described, where it is desired to have a very quick andonly temporary generation of steam.

Having thus described my invention, whatl claim as new, and desire tosecure by Letters Patent of the United States, is-
